Growing Cabbage in Peoria
Peoria sits in Zone 9b, with an average last frost of January 15 and first fall frost around December 31 — giving a 350-day frost-free growing season. Cool-season crops like cabbage benefit from Peoria's cooler spring and fall windows, when temperatures stay in the 55–75°F sweet spot that produces the best flavor and least bolting.
In Peoria's warm climate, cabbage works best as a fall, winter, and early-spring crop. Summer heat bolts most cool-season vegetables before they can produce a harvestable head or root. Plan primary plantings in October through February in Peoria, not April through June.
Peoria's caliche soil is rock-hard below the surface — raised beds filled with quality potting mix are the most practical approach for cabbage. Breaking through caliche for in-ground planting requires significant soil amendment, gypsum application, and deep tilling over several seasons. Water at 1.5 inches per week delivered through drip irrigation for best results in a raised-bed system.

Cabbage Tips for Peoria Gardeners
- •Space plants 18 inches apart — crowding reduces head size and promotes fungal disease.
- •Side-dress with nitrogen 3–4 weeks after transplanting to support rapid leaf formation.
- •Plant cool-season cabbage in Peoria during October through February — spring plantings bolt before producing a usable crop in warm zones.
Common Cabbage Pests in Peoria
- •Cabbage Worm — peaks June–August in Zone 9b (active March–October); green caterpillars on brassicas; apply Bt spray or use row covers.
- •Cabbage Looper — peaks June–August in Zone 9b (active March–October); loop-walking green caterpillars; Bt spray works well.
- •Aphid — peaks June–August in Zone 9b (active March–October); monitor closely during peak season and treat early.
Check plants every 2–3 days during peak season — early intervention prevents most infestations from becoming serious.
What to Plant with Cabbage in Peoria
In Peoria's warm climate, Onion and Dill are the most beneficial plants to grow alongside cabbage. Onion deters carrot fly, aphids, and several root-zone pests through sulfur compounds. Keep cabbage away from Tomato — it competes for nutrients or shares pest pressure. Warm-climate gardeners especially benefit from dense, layered companion plantings that shade soil and reduce water loss.

What zone is Peoria, AZ for cabbage growing?
Peoria is USDA Zone 9b. For cabbage, this means a frost-free growing season of roughly 50 weeks running from January 15 to December 31. Cool-season crops like cabbage thrive in this zone with both spring and fall planting windows available.
When is cabbage harvest season in Peoria?
Expect the first cabbage harvest in Peoria around February 23, with harvest continuing through April 4. This is based on 60–100 days from transplant or direct sow. A fall crop planted October 8–18 adds a second harvest around December 7.
How long does it take to grow cabbage in Peoria, AZ?
From transplant or direct sow to first harvest, cabbage takes 60–100 days in Peoria's climate. Based on a typical planting date of December 25–January 4, expect your first harvest around February 23. Peoria's warm Zone 9b climate tends toward the faster end of this range — warmer soil and longer days accelerate maturity.
What soil does cabbage need in Peoria?
Peoria's caliche subsoil is effectively rock — traditional in-ground planting of cabbage produces poor results.

Break through caliche only for deep-rooted crops, and expect to add compost each year to offset the alkalinity.
